Growth Response of Kopsia (Kopsia arborea Blume) Plants to Applied Endophytic Fungi

Abstract

The plant always associates with microbes for its life, includes the endophytes. Aim of this study is to examine the effect of endophytic fungi on Kopsia (Kopsia arborea) seed germination and seedling growth. Here, we used endophytic fungus from forest pathology laboratory, namely Phomopsis sp1, Phomopsis sp2, and Helminthosporium sp. All endophytic fungi were combined with liquid fertilizer to assess Kopsia seedling growth. The results showed that the Kopsia seed germinations, which treated with endophytic fungi have a higher value than the control. The endophytic fungi Phomopsis sp1 and Helminthosporium sp could increase the number of leaves without adding liquid fertilizer, while the Phomopsis sp2 needed liquid fertilizer for it. The NPA and the IMB values of the Kopsia seedlings are 0.71-1.71, and 0.18-0.33 strongly indicates the readiness of Kopsia seedlings to plant in the field, respectively.
